Fuel cell device

Abstract

A fuel cell device includes: a mixing tank in which a fuel is mixed with a fluid to produce a diluted fuel; a fuel cell that generates electricity by use of the diluted fuel; a flow path through which the diluted fuel is circulated between the fuel cell and the mixing tank; and a filter member that is disposed in the mixing tank and removes metal ions.

1 . A fuel cell device comprising: 
 a mixing tank in which a fuel is mixed with a fluid to produce a diluted fuel;    a fuel cell that generates electricity by use of the diluted fuel;    a flow path through which the diluted fuel is circulated between the fuel cell and the mixing tank; and    a filter member that is disposed in the mixing tank and removes metal ions.    
   
   
       2 . The fuel cell device according to  claim 1 , wherein the flow path comprises: 
 a diluted fuel flow path through which the diluted fuel is supplied from the mixing tank to the fuel cell; and    a recovery flow path through which the diluted fuel that is unused in the generation of electricity is returned from the fuel cell to the mixing tank, and    wherein the filter member partitions an interior of the mixing tank into:    a first compartment into which the diluted fuel that is returned from the fuel cell flows; and    a second compartment into which the diluted fuel from which the metal ions are removed by the filter member flows.    
   
   
       3 . The fuel cell device according to  claim 1 , wherein the mixing tank comprises: 
 a tank body; and    a cover member that closes the tank body, and    wherein the filter member is detachably attached to the cover member.    
   
   
       4 . The fuel cell device according to  claim 1 , wherein the filter member is immersed in the diluted fuel in the mixing tank.  
   
   
       5 . An electronic apparatus comprising: 
 a body; and    a fuel cell device detachably connected to the body,    wherein the fuel cell device comprising: 
 a mixing tank in which a fuel is mixed with a fluid to produce a diluted fuel;  
 a fuel cell that generates electricity by use of the diluted fuel;  
 a flow path through which the diluted fuel is circulated between the fuel cell and the mixing tank; and  
 a filter member that is disposed in the mixing tank and removes metal ions.  
   
   
   
       6 . The electronic apparatus according to  claim 5 , wherein the flow path comprises: 
 a diluted fuel flow path through which the diluted fuel is supplied from the mixing tank to the fuel cell; and    a recovery flow path through which the diluted fuel that is unused in the generation of electricity is returned from the fuel cell to the mixing tank, and    wherein the filter member partitions an interior of the mixing tank into:    a first compartment into which the diluted fuel that is returned from the fuel cell flows; and    a second compartment into which the diluted fuel from which the metal ions are removed by the filter member flows.    
   
   
       7 . The electronic apparatus according to  claim 5 , wherein the mixing tank comprises: 
 a tank body; and    a cover member that closes the tank body, and    wherein the filter member is detachably attached to the cover member.    
   
   
       8 . The electronic apparatus according to  claim 5 , wherein the filter member is immersed in the diluted fuel in the mixing tank.
